CUTTING APPARATUS FOR FILLED-BAG MACHINES.

Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed November 2l. 1905- Serial No. 288,467.

To all 'whom it may concern."-

.Be it known Athat we, CHESTER MCNEIL and DUDLEY S. SEYMOUR, citizens of the United States, residing at Chicago, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Cutting Ap aratus for Filled-Bag Machines, ot whic the following is a description, reference being had to the accompanyine drawing and to the letters and figures of re erence marked thereon.

iIy invention relates to an improvement in filled bag sewing apparatus, and particularly to an arrangement for severing the chain ot stitching between two successive sacks.

The object of' the invention primarily is to provide a cutting apparatu's'which shall be incapable of operation while abag is being. sewed, so that ii' for any reason the operator stops the machine by releasing her foot from the treadle, while a bag is beneath the sewing head, the cutter cannot operate to mutilate the'bag A The invention relates to that class of i'illed .bag sewing and delivering apparatus now well known, in which an endless carrier delivers illed bags in succession to a sewing head which overliangs the edge of a table or supporting framework, and in lwhich a cutting device while normally kept from operation while the foot of the 'operator is on the treadle yet is operated when the operator raises his foot from the treadle.

In an apparatus where some positive manipulating action of the operator is necessary to perform the cutting, or in devices where the movement of the bag beyond a certain point trips a mechanism to operate the cutter, it is not necessary to safeguard against the cutting of the bag by accidental operation of the cutter; but inan apparatus where the stopping of the machine when a bag is being sewed, either by accident or by design as when the threadsV break, would result in the operation of the cutter, auto inatically, it is desirable to provide means to prevent such.

The invention, therefore, consists broadly in the combination with a filled bag sewing and delivering apparatus, in which the sto ping of thesewing mechanism causes t e operation ofthe device for cutting the chain o stitching between the bags, of means con trolled by the movement of the bag, for

preventing the action of the cutting device while a bag is in engagement with the sewinv head.

econdly, the invention vconsists in the combination with a iilled bag sewing and delivering apparatus, in which the cutting apparatus' iscaused to Operate by the release of the manual means controlling the starting and stopping of the sewing mechanism, of means controlled by the movement of the bag for preventing the action of vthe cutting device,

while a bag is engaged by the sewing head.

Again, the invention consists in the combination with a illed bag sewing and delivering apparatus, in which. the cutting appa ratus is caused to operate by the release of 'the manual means controlling the starting and stopping of the sewing mechanism of a lever in the path of the bag connected with the cutting apparatus to break thel connections between said cuttingapparatus andthe said manual means, so long as the lever isin engagement with the bag.

Finally, the invention consists in the varius matters hereinafter described and referred to in the appended claims.

The invention is illustrated in the accompanying drawing, in which l Figure l is a perspective view of a filled bag sewing apparatus embodying my invention; Fig. 2 is a front elevation, illustrating' my improved cutting apparatus and the parts pertaining thereto; Fig. 3 is an end elevation; Fig. i is asimilar view, not so coniplete, Jtrom the opposite side from Fig. 3, partly in section; Fig. 5 is a plan view certain parts being shown in section Fig. 6 is a detail of the cutter blades and supports; Fig. 7 is a detail view of the cutter, Fig. 8 is a sectional view oi the parts shown in Fig. 7. Fig. 9 is a detail view of the yoke.

` The working parts of the machine are sup-- ported on a suitable frame A, to the top of which is secured an overhanging sewing head a, carrying'the usual mechanism o erated in the manner common to machines oi this type Below the sewing head is a vertically adjustable table b, over which runs an endless feed belt c, which is fed forward to carry the bags under the sewing head.

To the vertical arms d, which carries the looper shaft, looper and associated mechanisms, is secured a cutting blade e, held in f lace b two screws e c2 the latter screw iro j', which co-acts with the cutter e, in severing the Achain of stitching between successive bags.

- lnone type of bag sewing machines, the movable blade j', is;connected to and operates with the stopping and starting mechanism, and is under the control of a pedal or similar member, so arranged that when the foot of the operator is removed the pedal rises; the mechanism is stopped and the cutter moves to sever the chain. Y and its connections are clearly illustrated in Figs. 1 and 2, wherein G designates a driven shaft, on which is mounted a loose pulley g, and a tight pulley g, the pulleys being provided with suitable clutching faces and pulley g being movable into engagement with the pulley g, by means of the lower arm 7i of a three armed lever H pivoted on a stud 7i', carried by the fixed frame. A second arm 71? of tliis'lever carries a brake block i adapted to engage against a friction rim I on pulleyT g, and check its rotative movement.

The third arm i ofthe lever is connected by a vrod J to a rocker arm on a pedal rock shaft K, that is supported in bearings near the base of the machine, and carries a pedal L within convenient reach of the operator.

The loose pulley g, carries suitable belts through which motion is imparted to the stitching and feeding mechanisms, so that when the pedal is held depressed all parts of the machine operate, and when the operators foot is removed, the pedal is raised by a spring M, and the sewing and feeding operations cease, and at the same time operative movement is imparted to the movable cutter 7".

l ltrwill be seen that the mechanism will operate satisfactorily so long as the pedal is held depressed, while a bag is on the machine, and is only allowed to rise after a bag has passed the sewing head. Should the pedal rise while a bag is still under the head,

the bag will be mutilated, audit is this o eration which the present invention see (s to prevent.

Tp the front of the machine frame, above the bag-receiving platform, is lsecured a bracket or late 1, having a pair of lugs 2, provided with vertically alined openings for the rece tion of a pin 1, on which is loosely ,mounter a collar 5, having

arms

6 and 7, pro- "jecting in opposite directions respectively'. The arm 6 extends over the bag support, and

is provided with an adjustable fingerS, ar-

ranged in the path of movement ofthe bags.

To the upper end of the pin e, is rigidly secured a 'frame 9, havingv oppositely directed and rearwardly extending arms 10, having openings for the passage of a pivot bolt 11, thatis securely 'locked in place by a nut 12. Projecting from the rear of the frame 9 is a downwardl f curved arm 13, which is oonnected te t. e erin 7 by-a tension spring le,

This general mechanism and when this spring is placed under stress it tends to draw the arm 13 after it, and turn the frame 9 and in 4.."This movement, however, is resiste' by a torsion spring 17',1 extending around thein, and having one end -secured thereto, an the opposite endl to one of the lugs 2,.

. On the pivot boltl 11 is mounted a collar or hub'l, carrying 'oppositely directed

arms

17 and 18, the rearward extending arm-17 being arranged to entier a notch 19, formed in the end of the 'arm i', of lever H, and said arm has an overhanging lip 20, to insure proper engagement with the arm 17'. The forward and upwardly extending 'arm 18, lterminates in a yoke 22, between the two arms or ears of whichy is arranged a lug 23 carried by the movable cutter f. The arms ofthe yoke are connected by a pin 24, which belt wi l engage the projecting linger 8, and tend to move it inward toward the frame, and the finger will bev retained in this position so long as any part ofthe bag is beneath the sewing head. This'movement is transmitted through the arm 7, and spring 14, to the arm 13, and the frame 9 and pin 4 are turned against the resistance offered by the spring 17', and as a result the end of arm 17 isfheld out of notch 19 and remains dis-- connected from'the controlling lever Hand the pedal, until the bag being operated upon passes beyond the sewing head, whereupon the linger 8 is released, and the parts move to normal position, the end of arm 17 entering the notch 19, and then, when the edal is. released, operative movement wi l be transmitted to the'cutter.

Free movement of the arm 18 with respect to the cutter is permitted by the construction of the yoke 22 previously described.

Having thus described our invention, what we claim as'new and desire to secure by Letters Patent, is
